The Hollywood star's unflattering impression of the billionaire businessman on Saturday Night Live has proved a big hit with critics of the US President-elect.

But the parody struck a sour note with the Republican, who has slammed the show on social media as "boring and unfunny".

And Baldwin is not the only star Mr Trump has criticised on Twitter.

In his latest online rant, he taunted his reality TV successor Arnold Schwarzenegger for getting lower ratings than he did in his last season as Celebrity Apprentice presenter.

"Wow, the ratings are in and Arnold Schwarzenegger got 'swamped' (or destroyed)," Mr Trump wrote in a tweet on Friday.

"By comparison to the ratings machine, DJT," he added.

In a more diplomatic tone, Schwarzenegger responded a few hours later tweeting: "I wish you the best of luck and I hope you'll work for ALL of the American people as aggressively as you worked for your ratings."
